Hey there, I hope you’re having an awesome week! I just made a yummy protein smoothie to break my fast and wanted to share it with you. It’s quick and easy and super yummy!  I call it the Purple Cow Protein Shake but you can call it whatever you like.

Sure, Purple Cow isn’t original, but coming up with fun names for food is entertaining and you might like it too. I made a list of alternative recipe names for you to use below:

  • Fuchsia Fitness Fusion (Try saying that 5 times fast.)
  • Lavender Liquid Libation
  • Indigo Protein Power
  • Outstanding Orchid Mélange
  • Pleasant Plum Potion
  • Aubergine Bloom Brew

Just call me a word nerd. ha

Now, back to the recipe. Because I’ve been living the keto lifestyle I wanted to make it low in carbs. If you aren’t watching your carbs, feel free to add more fruit and/or use cow’s milk (full-fat, preferably). But, just in case you’re wondering, the net carbs are 9.5 g. (You can calculate net carbs by subtracting the total fiber from the total carbs.)

As you can see, I chose a plant-based milk to keep the carbs (and blood sugar) low. Protein shakes are great because you can personalize them and throw in your favorite ingredients based on the foods and flavors you love the most.


I would have added some leafy greens, like spinach or kale, but I need to go grocery shopping so I don’t have any on hand. Go for the greens and you’ll likely have a greenish-purple shake with tons of added nutrition!

Now, on to the good stuff…
